ILLUMINATED WATCH Filed April 22, 1958 Niamey United States PatentILLUMINATED WATCH Paul R. Vogel, Gentllod, Switzerland, assignor, bymesne assignments, to Fabrique des Montres Solvll 8r Titus S.A., Geneva,Switzerland Filed Apr. 22, 1958, Ser. No. 730,210 Claims priority,application Switzerland July 24, 1957 1 Claim. (CI. 58-50) The presentinvention relates to an illuminated watch comprising an electric bulbwhich is supplied with current from a battery.

This watch is characterised in that it comprises a circuit-breaker meansin the feed circuit of the said bulb, controlled by the winding crown,the latter being mounted so as to be movable axially on its stern, andthe whole arrangement being such that by pressing on the said crown, thebulb is lit up.

One form of embodiment of the subject of the invention is illustrated byway of example in the accompanying drawings.

Figure 1 is a plan view of a wrist-watch provided with an electric bulb.

Figure 2. is a sectional view on a larger scaletaken on the line II-IIof Figure 1.

Figure 3 is a partial sectional view on a larger scale, taken on theline III-III of Figure 1, and,

' Figure 4 is a partial sectional view, also on a larger scale, taken onthe line IV--IV of Figure 1.

The watch illustrated comprises a case formed of a middle-bezel 1, inwhich is fixed the glass 2, and a cover 3 which is screwed into themiddle-bezel with the interposition of a packing ring 4. The work 5 ofthis watch, provided with a dial 6, is fixed in the case through theagency of a mounting frame or ring 7 made of electrically insulatingmaterial. An electric battery 8 is lodged underneath the said work,between the latter and the cover 3. The battery bears on the one handagainst the mounting frame 7 and on the other hand against the cover 3with the interposition of an annular spring 9.

The mounting frame 7 which is made of insulating material, carries anelectric bulb 10 mounted in a hole 11 (Figure 3) and extending throughan aperture 12 in the dial. The frame 7 also carries two metal rings 13and 14, constituting the conductors for supplying current to the bulb10. The ring 13 is mounted on the face of the frame 7 which facestowards the cover and the ring 14 on the face which is situated adjacentthe dial, but

The electric battery 8 is so designed that one of its poles is connectedto its upper face 8a whilst the other pole is connected to its lowerface 8b. The face 8a is in contact with the ring 13 of the mountingframe 7, whilst the face 8b is in contact with the spring 9 andconsequently with the body constituted by the case and movement of thewatch.

The ring 14 can be connected electrically to the body owing to the factthat the winding crown 16 is mounted so as to be movable axially on itsstem 17. When pressure is exerted on the said crown, the end of thetubular shank 16a of the crown 16 comes into contact with a folded-overflange 14:: on the ring 14 and thus closes the feed circuit for thebulb, which lights up. A coil spring 18 is interposed between the crown16 and the case part 1 so as to urge the crown into the position inwhich the feed circuit of the bulb is open. Finally, it should be notedthat although the crown is movable axially on the stem 17, the crown isfast therewith in the angular sense by means of a grooved head 19 whichis fixed on the stem 17 and which is lodged in a correspondingly shapedinternal cavity 20 formed in the crown.

The rings 13 and 14 constituting the conductors supplying current to thebulb 10 can either be fitted on to the mounting frame 7, or may beconstituted by printed circuits.

What I claim is:

In an illuminated watch comprising an electric bulb the feed circuit ofwhich is supplied with current from a battery, a case, a clockwork insaid case, a winding stern, a winding crown axially movable on saidstern out angularly rigid therewith, a tubular shank rigid with saidcrown, a mounting frame surrounding said clockwork, said frameconsisting of insulating material on which said bulb is fixed, and twoconductors whereby current is supplied to the said bulb, one conductorbeing connected to one of the poles of the said battery and the otherbeing an extension situated opposite said shank of the said crown insuch a manner that the said shank comes into contact with the saidextension and thus closes the feed circuit of the electric bulb whenpressure is exerted on the crown, the second pole of the battery beingitself connected electrically to the body formed by the said case and bythe said clockwork.
